Barenbrug has done a lot of research into the fructan (sugar) contents of different grasses. Some grass species are known for their low fructan contents, but even within a species, some varieties contain more fructan than others. The varieties in Horse Master contain an impressive 50% less fructan than varieties of grass intended for cattle and sheep.
Barenbrug analyses the fructan contents of more than 70 grass varieties a year. The following graph shows you the great differences in the fructan contents of different varieties. The varieties in Horse Master contain on average less than half of the fructan that is to be found in cattle grass varieties.
